Abstract (en)
[origin: EP3839439A1] Systems (200), methods (400), and computer program products for sinusoidal nulling are provided. Aspects include transmitting (402), by a controller (202), an excitation signal to a first sensor, determining (404), by the controller, a target harmonic based at least on one or more characteristics of the excitation signal, receiving (406) a return signal from the first sensor, sampling (408) the return signal at a first sample rate based on the target harmonic, and adjusting (410) a phase of the sampled return signal to null the target harmonic amplitude to form an adjusted return signal.
